Description

Non-steroidal ligand and its application in gene switching regulation and control
Invention field
The present invention relates to the field of steroid chemical and gene controlled expression.More particularly it relates to the non-steroidal ligand of natural and mutation nuclear receptor, and their applications in the inducible gene expression system based on nuclear receptor.The invention further relates to the method using the goal of regulation and control gene expression in host cell of these parts and corresponding gene switching.The invention further relates to the composition containing one or more non-steroidal ligands and therapeutic combination.
Background of invention
All patents, patent application and the publication that the present invention is quoted integrally are all fully incorporated by reference herein.
Precise control gene expression is research, manipulates and control development and the valuable instrument of other physiology courses.Gene expression is related to a large amount of specific protein-protein interactions.DNA is transcribed into the activating transcription factor that RNA is related near the promoter of control genetic transcription.Generally, activating transcription factor is combined with a protein, and this protein has the DNA binding structural domains being combined with the site of gene promoter region.In order to produce gene expression, the albumen with DNA binding structural domains and transcriptional activation domain must be brought to the correct position of gene promoter region.
A kind of transgenic method drives the expression of transgenosis using cell type specific promoters.DNA constructions with transgenosis have been incorporated into host genome first, and when being transcribed activity factor triggering, the expression of transgenosis occurs in given cell type
Another method is by inducible promoter.Example includes the eukaryotic transcription activation system such as steroid hormone receptor system of PR-1a promoters, protokaryon repressor/operon system, immunosupress immunophilin system, and higher grade.
(Wurn etc., 1986, Proc.Natl.Acad.Sci.USA 83 are had been described based on the gene regulatory system by heat shock, interferon, the promoter of heavy metal induction:5414-5418;Arnheiter etc., 1990Cell 62:51-61;Filmus etc., 1992Nucleic Acids Research 20:27550-27560).However, because they are for the influence of the expression of non-target gene, these systems are leaky and have a limitation.
Protokaryon repressor/operon system is using bacterium repressor albumen and its unique operator DNA sequence dna combined.Tetracycline (" Tet ") and galactolipin (" Lac ") repressor/operon system from bacteria Escherichia coli have been used in plant and animal control the expression of gene.In Tet systems, tetracycline is attached to TetR repressor albumen, causes conformational change, and repressor albumen is discharged from operator, so that transcription occurs.In Lac systems, the presence to galactolipin or the analog of synthesis such as isopropyl ss-D- thiogalactosides produces response so that lac operators are activated.Using such system in plant and animal, the chemical instability of part (tetracycline and galactolipin), their toxicity, they naturally occurring are limited to, or induction or suppress to need of a relatively high level.
Immunosuppression molecule such as FK506, rapamycin and ciclosporin A can be incorporated into immunophilin FKBP12, cyclophilin on.Utilize this information, a kind of whole strategy taken any two albumen to together is devised, can be simply by FK506 be put into each in two albumen, or by the way that FK506 is placed on an albumen and ciclosporin A is put on another.It is then possible to which the compound (FKCsA) that homodimer (FK1012) or FK506- the cyclosporines fusion synthesized using FK506 is produced, induces dimerization (Spencer etc., 1993, Science 262 of these molecules:1019-24;Belshaw etc., 1996Proc Natl Acad Sci U SA93:4604-7).Using the Gal4DNA binding structural domains for being fused to FKBP12 and the VP16 activator domain for being fused to cyclophilin and FKCsA compounds, show as dimerization and activate the reporter gene under the control of the promoter with Gal4 binding sites.This system includes the immunodepressant that can have harmful side effect, limits the application in mammalian genes switch.
Transcriptional activation system such as steroid hormone receptor system has also been used.Steroid hormone receptor is the member of nuclear receptor superfamily and is present in vertebrate and spinal zooblast.
The growth of insect, cast off a skin and develop regulation and control (Dhadialla etc., 1998.Annu.Rev.Entomol.43 by cast off a skin sterol hormone (moulting hormone) and juvenile hormone:545-569).The molecular target of sterol of being casted off a skin in insect includes casting off a skin sterol acceptor (EcR) and super valve albumen (USP).EcR is a member of core steroid receptor superfamily, and the superfamily is characterised by significant DNA and ligand binding domains and an activation structure domain (Koelle etc. 1991, Cell, 67:59-77).EcR acceptors include commercially available tebufenozide to multiple steroids such as ponasterone A and meter Le sterones A and non-steroids and methoxyfenozide produces response (referring to PCT/EP96/00686 and US 5,530,028).
Insect molting sterol acceptor (EcR) and super valve albumen (USP, mammal RXR insect homologue) occur Heterodimerization, with reference to sterol of casting off a skin, with reference to sterol receptor dna response element of casting off a skin, and the transcription for sterol response gene of casting off a skin is activated.EcR/USP/ ligand complex plays a significant role in insect growth and reproductive process.EcR is a member of steroid hormone receptor superfamily and has 5 control domains, (DNA is combined by A/B (trans-activation), C, Heterodimerization), D (hinge, Heterodimerization), E (ligand binding, Heterodimerization and trans-activation) and F (trans-activation) domain.When being fused on other albumen, some of these domains, such as A/B, C and E remain their function.
The inducible gene expression system or " gene switching " strictly regulated and controled can be used for various applications, the extensive generation of such as gene therapy, albumen in cell, the test of the high flux screening based on cell, functional genome, and in genetically modified plants and animal characteristic regulation and control.
A kind of gene switching based on EcR uses Drosophila melanogaster EcR (DmEcR) and home mouse RXR (MmRXR), and show reporter gene (the Christopherson K.S in these receptor transactivation mammal cell lines and transgenic mice in the presence of steroids, ponasterone A, Mark M.R, Baja J.V, Godowski P.J.1992, Proc.Natl.Acad.Sci.U.S.A.89:6314-6318;No D, Yao T.P, Evans R.M, 1996, Proc.Natl.Acad.Sci.U.S.A.93:3346-3351).Later, Suhr etc. 1998, Proc.Natl.Acad.Sci.95:7999-8004 shows that tebufenozide passes through the reporter gene in silkworm EcR (BmEcR) trans-activation mammalian cell when lacking external source heterodimer companion.
The method that PCT/US97/05330 (WO 97/38117) and PCT/US99/08381 (WO99/58155) disclose regulating expression of foreign genes, wherein in the presence of part and alternatively can be in the presence of the acceptor as silence companion, the DNA constructions comprising foreign gene and sterol response element of casting off a skin be by a sterol receptor activation of casting off a skin.Cast off a skin what sterol acceptor was separated from Drosophila melanogaster.Generally, such system needs the presence of silence companion, for example Retinoid X Receptor (RXR), to provide optimal activation.In mammalian cell, insect molting sterol acceptor (EcR) and Retinoid X Receptor (RXR) Heterodimerization, and regulate and control in the way of ligand-dependent the expression of target gene.PCT/US98/14215 (WO99/02683) discloses the sterol acceptor of casting off a skin separated from silkworm silkworm moth and played a role in mammlian system, without external source dimer companion.
The various members that US 6,265,173B1 disclose various steroids/thyroid gland superfamily receptors can be combined with Drosophila melanogaster USP or its fragment with least one USP dimerization domain, for a gene expression system.US 5,880,333 discloses Drosophila melanogaster EcR and USP a heterodimer system being applied in plant, and wherein transactivation domain with DNA binding structural domains is located on two different hybrid proteins.These systems based on USP are composing type in zooblast, so being unable to the expression of Effective Regulation target gene.
At each occurrence, transactivation domain and DNA binding structural domains (can be such as the natural EcR in the PCT/US98/14215 or EcR such as the modification in PCT/US97/05330) are incorporated into individual molecule, and other heterodimers companion, USP or RXR, is used with their native state.
The shortcoming of the above-mentioned gene regulatory system based on EcR has considerable background vigor when being included in shortage part, and these systems are unable to plant and animal and are all suitable for (referring to US 5,880,333).
So, this area needs to improve the system based on EcR, and accuracy controlling is endogenous in plant and animal or expression of external source target gene.The system so improved can be used for following application, such as gene therapy, large-scale production albumen and antibody, high flux screening based on cell are tested, functional genome and in transgenic animals characteristic regulation and control.It is good and insensitive to steroids such as such as endogenous steroids to non-steroidal ligands response for some application such as gene therapies, it would be desirable to there is the gene expression system of an induction type.Therefore, simple, complicated and dependent on part improved system can be used for regulation and control biosystem, and the part is relatively cheap, be readily available and low to host toxicity.
Have shown that a kind of inducible gene expression system based on nuclear receptor, wherein they are separated from each other by the way that trans-activation and DNA binding structural domains are placed on two different albumen, so that background vigor when lacking part is substantially reduced, and vigor will be significantly higher than background (PCT/US01/09050) when there is part.Compared with the system disclosed in application PCT/US97/05330 and PCT/US98/14215, this two-hybrid system is a significantly improved inducible gene expression regulator control system.This two-hybrid system make use of a pair of interaction proteins that transcriptional activation domain is brought in into a position more favourable relative to DNA binding structural domains, so that when DNA binding structural domains are attached on the DNA binding sites of gene, transactivation domain more effectively activating promoters (referring to such as US 5,283,173).In brief, double cross gene expression system includes two expression casettes, and first assembly encodes a DNA binding structural domain being fused on nuclear receptor polypeptide, and the second component encodes a transactivation domain being fused on different IPs receptor polypeptides.When there is part, the first polypeptide and peptide interaction more than second effectively connect DNA binding structural domains and transactivation domain.It is located at because DNA is combined with transactivation domain on two different molecules, the background vigor when lacking part is substantially reduced.
In addition, two-hybrid system avoids some due to side effect caused by RXR is overexpressed generally occurring when unmodified RXR is used as switch companion.In one embodiment of two-hybrid system, the n DNA for eliminating EcR or RXR is combined and transactivation domain.As a result, these hybrid molecules and other steroid hormones interaction of intracellular presence are reduced, and cause side effect to reduce.
With the improvement of the gene regulatory system based on acceptor, for the increase in demand of the part higher than existing ligand activity.The invention discloses the new non-steroidal ligand that can adjust transgene expression, discussed referring to SilviaLapenna special topics, Britain.

ADME properties.Octane-water partition coefficient (MlogP) of steroids O- alkyl ether analogs is to zoom in and out to determine by the MlogP values of the non-ethers sterol to above calculating.By membrane interaction QSAR (MI-QSAR) model of foundation, to determine Caco-2 cell-penetratings coefficient and blood brain barrier distribution coefficient.MI-QSAR analyses include, in the descriptor pond for developing QSAR models, clearly from the property and feature for simulating every kind of dissolved matter (small molecular organic compounds) transhipment, the dissolved matter includes the training set through the model membrane structure being made up of phosphatide, is in this example dimyristoyl phosphatidyl choline (DMPC) molecule.Analyzed using 3D-FEFF-QSAR, assess the combination of steroids and human serum albumins (HSA).This method calculates the free energy Δ G that steroidal ligands are attached on HSA, and scoring functions are used as using proportional QSAR models.Ka values are obtained from Δ G=RT ln (Ka).Ka=(1/Kb), wherein Kb are binding affinity of the molecule to HSA, it is assumed that with reference to HSA generations are specific to, form binary complex, and there is excessive HSA ([HSA]=0.6mM) compared with ligand concentration.The water-soluble of steroids O- alkylated analogs is determined with AMSOL methods and software.
Physico-chemical tests LogD is detected by adsorption system company (Absorption Systems, Inc).In 1.5mL shaking flask systems, ponasterone A and 20E are 100 μM in isometric pH7.4 buffer solutions and water saturation octane, and multiple holes are detected, standard items are used as using testosterone.Then each shaking flask placed 1 hour at room temperature in shaken at room temperature 60 minutes.The organic layer and water layer being serially diluted are prepared, and coordinates minimum 4 point calibration curve to determine the test compound concentration of each dilution factor with common LC/MS/MS methods.Water solubility is detected by Robertson-Microlit companies.The saturated aqueous solution sample of the happy sterone A of PoA, 20E, rice and diacyl hydrazide is dissolved in HPLC grades of water, stirs 1 at 25 DEG C, 5 and 10 days, is then filtered to obtain the solution of clarification with 0.45 μm of filter.For every kind of material, respectively in 249,248,239nm and 219nm detection ultraviolet absorptivities, it is diluted if desired.Absorbance and reference standards are in the absorbance of identical absorbance maximum, the 1-2% solution of identical steroids in methanol, because solvent effect allows the maximum displacement for having until 10nM.
Synthesize 23 steroids O- alkyl ethers (Fig. 2), include content most abundant insect moulting hormones 20E (25) derivative;The derivative of maximally effective natural one of sterol PoA (26) of casting off a skin;With a kind of derivative of the activator Dacryhainansteronc (27) of the moderate strength with distinguished core texture.20E derivative is 5 kinds of monomethyl ether (1-4 in 2-, 3-, 14-, 22- or 25-OH site, 10), 4 kinds of dimethyl ethers (11-14) in one of 22-OH and 2-, 3-, 14- and 25-OH site, and a kind of tetramethyl ether (15).PoA derivatives are included in 2-, single oxygen methyl ether (16-18) in 14- or 22-OH sites, and 3 with a bis ether functional group kinds of analogs (19-21).In addition to methyl ether, it is prepared for several 20E22-O- ethers analogs, including with until four carbochains O- alkyls (5,6 and 8), and pi-allyl (7), benzyl (8) and 2 '-ethyl epoxy ethyl (23) ether group analog.It can be obtained in the importing methyl of indivedual hydroxyl group sites selectivity by the protection/deprotection strategy shown in Fig. 1, it is related to 2,3- is cis- and/or 20,22- glycol group are converted into acetonide or phenylboric acid salt groups.Can be by the one-pot reaction method since unprotected sterol of casting off a skin come while the analog (16,17,19,20) for preparing monomethylation or methylating more.This method is advantageous in reaction times, but needs carefully to carry out the reaction monitoring of HPLC- drivings, and to cause to methylate higher to the ratio of monomethylation analog more.It is being related to Ag2O and CH3In I methylation reaction, the reactivity order for sterol hydroxyl of casting off a skin is 22-OH > 2-OH > 3-OH > > 14-OH.When with Ag2O/CH320E when methylating of the 3rd cis-position 25-OH is not observed in I, by improving the amount of reaction temperature (until 60 DEG C) or reagent, 14-OH can be converted into CH3O- groups.However, Ag2O excess significantly or extend contact time, product degradation can be caused, such as dehydration and/or chromophore change.As an appropriate example, at room temperature, extend PoA and Ag2O/CH3After I time of contact (46 hours), it was observed that foring with the chromophore (7,9 (11)-diene -6- ketone groups), the PoA derivatives that methylate of DaH 22- methyl ethers (22) changed.The reaction mechanism of hypothesis can relate to by Ag2O removes one of two 11-H atoms, and then conjugated double bond is to migration.Finding suitable for the replacement O- methylation methods of the chemosensitivity molecule such as sterol of such as casting off a skin, we have found that 6 equivalents, under every kind of 25 DEG C and anhydrous condition in trifluoromethayl sulfonic acid methyl esters and DTBMP, it is steady and selectively promote 20E 2, the 25-OH of 3- acetonides (25b) methylates, and reactivity order is 25-OH > 22-OH > > 14-OH.This method represents a kind of method methylated for the O- of polyhydroxylated steroids newly developed.In our all experiments, 20-OH sites are still difficult to be methylated.
NMR. prepare O- alkyl and cast off a skin sterol 1-23 relative to its parent compound (20E, PoA or DaH)1H and13C spectrum are distributed, and1H-1H COSY,1H-13C HMQC and1H-13Detection J is of coupled connections in C HMBC spectrums.In 2-, the second ether substituent in 3- and/or 22- sites1H signal shows a characteristic High-Field displacement in about 0.4ppm, and with13C signal is related, described13C signal casts off a skin sterol in about 10ppm generation low field displacements relative to parent.With 14 α-OCH3The steroids of group is easily from theirs1Recognized on H-NMR collection of illustrative plates, wherein 9 α-H signal shows about 0.3ppm High-Field displacement (δH=2.76-2.78ppm), and they13C-NMR collection of illustrative plates, wherein 14-C signals show about 6ppm low field displacement (δC=90.95-90.98ppm).α-spatial chemistry of 14- methoxyl groups is confirmed by the irradiation of 9 α-H signal in NOESY experiments, causes 14-OCH3Signal enhancing 3% (2.97ppm) and 2 α -13% (3.53-3.81ppm) of H signal enhancing.20E 25- methyl ether analogs show an about 5ppm of the 25-C signals (76.16ppm) relative to 20E low field displacement, an about 4ppm of 26-C and 27-C signals (25.52and 25.27ppm) High-Field displacement.In sterol methyl ether analog of casting off a skin1In H-NMR collection of illustrative plates, from 2 β-OCH3, 3 β-OCH3, 14 α-OCH3, 22-OCH3And 25-OCH3Unimodal respectively appear in 3.39,3.40,2.97,3.50 and 3.19ppm.In 20E 22- ethylethers, propyl ether and butyl ether analog1H-NMR collection of illustrative plates, two protons being connected on the α carbon of 22-OR bases show as diastereo-isomerism signal, δHFrom 3.51 to 3.75ppm.231In H-NMR collection of illustrative plates, corresponding to 63.54ppm's13C signal, two of 3.49ppm and 3.39ppm it is bimodal (2J=12Hz) it is assigned to the paired epoxy ethyl proton of 22- ethyl epoxy ethyls;The 4th of 23 O-C-O groups13C signal falls in 110.25ppm.
Fruit bat BIICell tests (Fig. 3).Drosophila melanogaster BIICell naturally expresses natural EcR-USP compounds and specificity and quantitative reaction is made to EcR activators and antagonist.O- alkyl steroids 1-23 is in BIIAgonist efficacies are shown in biological test, concentration range is from 100 μM to 1nM, depending on the quantity of ether substituent and position in molecule.Especially, 20E 2-, 3-, 14- and 25- hydroxyl methylates so that effect is reduced, but 20E 22- methyl ethers (4) remain 20E effect.22- ethylethers analog (5) is more lower slightly than the effect of methyl, and as propyl group, pi-allyl and butyl etc. (6,7,8) alkyl group is bigger, activity difference rises.However, 22-O- benzyl substituents (9) will not be such that 20E effect declines a lot.O- alkylations of the PoA in any site reduces it in BIIEffect in biological test.
It is engineered EcR/RXR:USP gene switchings.The ability that O- alkyl steroids drives gene expression is detected in the mouse cell lines for the component for having turned inducible type systems in wink.It is main to use two kinds of gene switchings:One Spruce budworm (Cf) EcR (wt-CfEcR-DEF) and another E274V/V390I/Y410E mutant (- CfEcR-DEF of mutation) based on this receptor based on wild type.Coordinate some steroids, the experiment similar with fruit bat (Dm) EcR progress of the yellow fever mosquito (Aa) to identical gene switching pattern.People RXR β and insect USP from migratory locusts are fused on VP16-AD, and the chaperone as EcR.
Assess the effect (EC of steroids50) and effect.The latter, RMFI is calculated as the maximum fold induction in its optimal test concentrations under the conditions of same test relative to on-steroidal diacyl hydrazide EcR activators (30), the maximum fold induction of test ligand.Test and with reference to part fold induction be defined as part induction gene expression and DMSO control induction gene expression multiplying power.
In wild type-CfEcR gene switchings, PoA (26) shows highest induction vigor (EC in surveyed steroids50=0.19 μM, RMFI=~0.18), and the happy sterone A of rice and relatively low (the respectively EC of carinula element B effect50=7.4 μM and~12) and 20E is inactive (EC 5033 μM of >).After any site O- alkylations, PoA effect declines, although PoA 22- methyl ethers (18) and Dacryhainansteronc 22- methyl ethers (22) are provided than PoA (RMFI=~0.2) higher fold induction (respectively RMFI=~0.6 and~0.3) in itself.One special 20E O- alkylated analogs, 20E 22- ethylethers (5) reach the 77% of maximum fold induction in about 5 μM of concentration induced reporter genes.
In the CfEcR gene switchings that E274V/V390I/Y410E is mutated, PoA and PoA 22- methyl ethers are the steroids (Fig. 4) put up the best performance:PoA EC50It is worth for 0.1 μM, the EC of PoA 22- methyl ethers500.7 μM of value, and RMFI values are respectively 0.52 and 0.58.In this switch, the happy sterone A of rice is relatively weak, EC50For 1 μM;And carinula element B is~7 μM.20E is a very weak activator (EC50=20 μM).But after 22- ethylizations, 20E effect is significantly improved, EC50(5 be 0.76 μM;20E be~20 μM) and RMFI (5 be 1.1;20E is 0.12) to improve.Although degree is relatively low, 20E 22- n-propyls (6), 22- butyl (8), 22- benzyls (9) and 25- methyl (10) ether also improve the performance of their parent compounds, and the vigor of 20E 22- allyl ethers (7) is identical with 20E.Therefore, in the CfEcR gene switchings of wild type and E274V/V390I/Y410E mutant forms, PoA 22- methyl ethers are most strong O- alkyl ethers and 20E 22- ethylethers are to be number two.
Some O- alkylation steroids is tested also in the gene switching of same common version, and in addition to the E274V/V390I/Y410E CfEcR being mutated and VgEcR/RXR, wild type AaEcR or wild type DmEcR instead of CfEcR.In the test based on AaEcR- and DmEcR-, the effect sterone A more happy than rice of PoA 22- methyl ethers strong and more stronger than PoA (is respectively EC50=0.38nM and 66nM).For effect, AaEcR systems are all more more sensitive to the standard items PoA (1.1nM) and the happy sterone A (9nM) of rice of PoA 22- methyl ethers and test than CfEcR, but sensitivity is relatively low for effect (for example, PoA:In 1 μM of FI=166 [AaEcR] in 1 μM~900 [CfEcR]).This species diversity is largely that, simply due to AaEcR systems are higher (FI=7.6 [AaEcR] is to 0.7 [CfEcR]) in the background level of "Off" state, rather than the definitely expression of reporter gene is relatively low (RLUs=~1046 [AaEcR] is to 540 [CfEcR]).Relative to AaEcR switches, DmECR switches are more closely similar to CfEcR switches for background transcription, and response is lower in effect.In 3T3 cells, the VgEcR/RXR switch forms above developed are induced by PoA and meter Le sterones A, respectively EC50=0.641 and 0..851 μM, and the EC induced by PoA 22- methyl ethers50=0.553 μM.In comparing, the gene switching based on AaEcR- and DmEcR just produces response in low (AaEcR) and medium (DmEcR) nanomolar concentration to these parts, shows that effect is significantly improved.
Final 3D-QSAR models.The different molecular fields combination of selection, including the three-dimensional fields of CoMFA and electrostatic field, CoMSIA H- key donors, H- keys acceptor and hydrophobic field, and polar surface area (PSA), are casted off a skin sterol library with best representative.The statistics of the 3D-QSAR models of gained is summarized in fig .15.
Steroids and EcR gene switchings in gene therapy.EcR gene switchings are verified to be used in cell and tissue culture, and animal model.Effect highest part is main to be represented by two kinds of chemical types:The steroids of the diacyl hydrazide of synthesis and natural typically plant origin.Representative in two groups has all been used successfully in the EcR gene switchings in scale-model investigation.From the point of view of bioavailability angle; diacyl hydrazide has II type ADME characters (solubility is low, and logP is high, and permeability is high) and the site not almost being metabolized easily; and sterol solubility of casting off a skin is higher, logP is relatively low and has many hydroxyls for being easily metabolized or being coupled.
The O- alkyl for having synthesized 23 kinds of 20E, PoA and DaH is casted off a skin sterol analog.Obtain 20E and PoA all monomethyl ethers, except (a) PoA 3- methyl ethers, can only be methylated with 22- together with obtain, and (b) 20- methyl ethers, because verified 20- hydroxyls do not have reactivity.Common synthesis is depended on respectively to 2,3- and 20, the perfect ketal and borate glycerol protection strategy of 22- glycol groups.Synthesize 20E 22- methyl ethers (4) and 22- ethylethers (5) and separate 20E 25- methyl ether (polypody sterones, 10 from fern iron fan princess Polypodium aureum L.) had been described before this research, but gene switching test is not used it in past research.
Cytogene switch testing has used two kinds of gene switching patterns to test ether 1-23 gene switching effect, and simply have studied with several parts the 3rd pattern.First is natural fruit bat BIICell line.BIICell line derives from the haemocyte of tumprigenicity haemocyte mutant (l [2] mbn).BIISignal of the steroids as an induced phagocytosis is added in cell, and cell develops into the larger cell mass with clear area from cellule layer.This response can be quantified with turbidity.
Second of gene switching pattern is the heterodimer pair of engineering.It employs EcR ligand binding domains and is connected on bacterium GAL-4DNA binding structural domains, once it contact part, and locust-people RXR that the heterozygosis in the activation structure domain of virus VP 16 is connected to one is combined.This compound is subsequently incorporated on the GAL-4 response elements of luciferase reporter gene upstream, and the expression of luciferase reporter gene provides a fluorescence reading.Whole switching system is the transient expression in mouse 3T3 cells.The EcR-LBD variants for having used this to switch, wherein LBD sequences derive from choristoneura fumigerana (Spruce budworm, CfEcR), Aedes Aegypti (mosquito, AaEcR) and Drosophila melanogaster (fruit bat, DmEcR) (Fig. 8).In addition, the discovery of testing over can improve the CfEcR mutation variants (E274V/V390I/Y410E) of entirety EcR part sensitivity.In each case, all other composition of test system is consistent, except testing several steroids in different 3T3cells clone.
The 3rd gene switching pattern for several compounds is the VgEcR/RXR systems from DmEcR in the past for mouse In vivo study.
The QSAR of steroids is quantified --- and 22-O- alkyl sterol of casting off a skin retains or improved the induction vigor of their parent compounds.According to whether there is one or more methyl caps to anchor point, steroids is matched, and calculate fruit bat BIIEffect difference (Fig. 6) in test.With the relation between 2-, 3-, 14-, the single ether substitution in 22- and 25- sites 20E and PoA ether derivants (1-10,16-18,22-23) can immediately arrive at effect difference and specific OH-group group caps.On an average, methylating for each hydroxyl group sites causes effect to reduce, according to following EC50The suppression order of log units sorts:14-OH (2.12), 2-OH (1.67), 25-OH (1.09), 3-OH (1.06) and 22-OH (0.35).It may be evident, however, that the 22- for having 5 in 9 steroids methylates, including 20E (4 ,-logEC in itself50=8.20) so that effect is moderately improved.Multiple methylate usually enhances its effect.
The gene switching system of engineering all shows some difference responses in effect and SAR details.In the steroids tested on wild type CfEcR, only 20E 22- ethyoxyls ether 5 shows effect and significantly improves (EC than 20E50=485 μM, RMFI=0.77), 20E is a substantially inactive steroids in this test.In the CfEcR gene switchings test that E274V/V390I/Y410E is mutated, 5 constitute a sizable improvement (EC again50=0.76 μM, RMFI=1.10) relative to parent 20E (EC50=~20 μM, RMFI=0.12).Other 22- ethers, such as n-propyl ether and benzylic ether will also result in improvement.Unexpectedly, the happy sterone A of rice and carinula element B all in the gene switching of CfEcR patterns than in BIIIt is weaker in test.
For wild type CfEcR, once hydroxymethylation, PoA just loses effect and effect.But for CfEcR E274V/V390I/Y410E mutant, efficient PoA (EC50=0.10 μM, RMFI=0.52) loss of effectiveness it is much smaller, and also in fact obtain after 22- methylates effect (18, EC50=0.70 μM, RMFI=0.58), so as to obtain required effect, metabolism and Penetration Signature.AaEcR and DmEcR in identical two-hybrid system of this trend in mouse 3T3 cells have continued.Coordinate AaEcR, in (the EC of 1.10nM 1850=0.38nM) it is higher than PoA effect;Coordinate DmECR, it is equivalent in~66nM.However, in the VgEcR/RXR systems based on fruit bat, the 18 higher (EC of equal with PoA and meter Le sterone A effect or possible effect50=533nM/RMFI=1.5 is to being respectively EC50=641nM/RMFI=1.5 and EC50=851nM/RMFI=1.3), so as to be considered to be the optimal ligand of the system.In brief, PoA can methylate in 22- sites, produce the structure for lacking a hydroxyl but remaining vigor.Further, since the physicochemical property of methoxylation structure should be more preferable, it may be more potential in itself than PoA in treatment use.We show that 22-O- alkyl (methyl, ethyl, propyl group) and 22-O- benzyl steroids remain or improved the induction vigor of their parent compounds.
ADME.Sterol ether of casting off a skin has a good ADME feature.For exemplary steroids ether and reference composite thing, the several ADME characters-water solubilitys of calculating, LogP (MlogP), blood brain barrier (BBB) are penetrated, Caco-2 cell permeabilities and human serum albumins (HSA) combine (Fig. 7).
Solubility.The value that the PoA and 20E of calculating are water-soluble with experiment is obtained is consistent (being respectively 0.18mg/mL and 6.7mg/mL).Generally, solubility is improved (the happy sterone A > 20E > PoA of such as rice) with hydroxyl quantity;Correspondingly, hydroxyl, which is capped, generally reduces solubility.Noticeable exception is 20E22- alkyl ethers.For example, the solubility outline of steroids 5 (20E 22-O- ethyoxyls ether) and 7 (20E 22-O- allyl ethers) is higher than their parent compounds with free 20,22- glycol.One explanation is, compared with 22- alkyl analogs, and the intramolecular hydrogen bond of 20E 20,22- glycol causes the reduction of hydrotropy intramolecular hydrogen bond, and it is only involved in the effect of 20-OH donors/22-OH acceptors, and is limited by more thermokinetics with solvent hydrogen bond.In a similar manner, 22-OH/25-OH intramolecular hydrogen bonds effect may also be significant.Methylated the intramolecular hydrogen bond in having upset 22-OH donors/25-OH receptor actings in 20E O-22, smaller to PoA than PoA22- methoxy-ether is suppressed to the water-soluble of 20E so as to result in 20E 22- methoxy-ethers, PoA lacks 25-OH, so such intramolecular hydrogen bond can not be formed.For diacyl hydrazide 30, to calculate and differ~3 orders of magnitude between water-soluble (3.6mg/mL) and observation water-soluble (6.2 μ g/mL).Experimentally, diacyl hydrazide is the material easily crystallized.Possible this solubility contradiction discloses the physical behavio(u)r that a MI-QSAR model does not illustrate.
Mlog P valuesAs water solubility, MlogP values are identical with alkylation trend.Equally, 22- alkylations are an exceptions;For the reason for trend identical intramolecular bond water-soluble with influence, the alkylation in this site can actually reduce MlogP.MlogP has over-evaluated experiment value:20E logDExperiment=0.01 (logPCalculate=1.25);PoA logDExperiment=1.95 (logPCalculate=2.19).
Blood brain barrier separatesMolecule is the logarithm (logBB) of BBB partition coefficients through the measurement of BBB abilities, and it is equal to log (CBrain/CBlood), wherein CBrainIt is concentration and C of the compound in brainBloodIt is the concentration of compound in blood.Experimental data is separated according to the BBB delivered, log (BB) values > 0.3 shows that compound is easily accessible in brain, and log (BB) values < -1 shows that analysis is hardly entered in brain.Our ADME estimations show that moderately distribution enters in brain (- 0.89 < log (BB) < -0.35) 20E, PoA and meter Le sterone A.On the other hand, O- alkyl ethers sterol shows the ability raising through BBB, especially PoA 2- methyl ethers (16:Log (BB)=0.16) and PoA 22- methyl ethers (18:Log (BB)=0.23).For potential central nervous system (CNS) therapeutic agent, it is desirable to log (BB) be on the occasion of.Equally, calculating log (BB) value of 20E O- alkyl ethers analog is higher than 20E.
PermeabilityCaco-2 infiltration coefficients (the P of some steroidsCaco-2) determined using the Caco-2 Premeabilisation of cells QSAR models set up.As shown in Figure 7, from rice happy sterone A to 20E to PoA, PCaco-2Value gradually increases, while molecule lipophilicity (MlogP values) increase and water-soluble reduction.With parent molecules PoA (19 × 10-6Cel) to compare, PoA O- alkyl ether derivatives 16,18 and 20 show equal or higher PCaco-2Value is (from 20 × 10-6To 29 × 10-6Cel);With parent compound 20E (16.3 × 10-6Cel) to compare, 20E O- alkyl ether derivatives 4,5,7,10 and 14 are also equivalent or are easier infiltration Caco-2 cells (14-24 × 10-6Cel).These results show to cast off a skin oral bioavailability of oxygen-ether derivant of sterol is improved.

Supported in hole 21-28 days, test steroids, pH 7.4 ± 0.2 are all added in top side and bottom side.At 120 minutes the permeability of top side-bottom side (A-B) and bottom side-top side (B-A) was determined from every side draw sample.Minimum four point calibrations curve is coordinated to detect the concentration of test compound using common LC/MS/MS methods.It is characterized as (Papp A → B) < 1.0 × 10-6It is low that the material of cel is considered as permeability.More than this value, then permeability is high.If flowing out > 3.0 and (Papp B → A) > 1.0X10-6Cel, it is believed that material there occurs obvious outflow;B)Plasma protein binding test:Dialyse hole (n=2), each dialysis hole side carries pH 7.4 phosphate buffer solution, the opposite side in hole carries the other human plasma of Combination, adds test steroids.After 37 DEG C, about 24 hours, the blood plasma side and buffer solution side in each hole are sampled, and is analyzed with LC/MS/MS.These experiments are carried out by absorption system Co., Ltd (Absorption Systems, Inc), and the results are shown in Table 8.

Plasma protein is combinedHSA binding affinities are drug discovery and the important pharmacokinetic property considered in exploitation.HSA combines the dissolving that allow for hydrophobic molecule in the circulatory system.Compound is to determine that compound is distributed to one of destination organization and his principal element of bioavilability with sero-abluminous bond strength.As shown in fig. 7, sterol of casting off a skin shows similar HSA binding affinities, from 2.1 × 10-4To 3.8 × 10-4(Ka values).It is 20E 22- ethylethers (5) that HSA, which combines minimum compound, in set, and it is also that MlogP values are minimum and water-soluble highest of calculating in the ether of set.It is PoA 3 that HSA, which combines most strong compound, 22- dimethyl ethers (20), and it is also MlogP values highest and to be in the calculating in the relatively low scope of water solubility of sterol of casting off a skin in the ether of set.Therefore, cast off a skin sterol HSA combine it is universal related between the hydrophobicity and water solubility of compound.
Metabolism and excretion.The half-life period that 20E is estimated in the mankind is 9 hours.Known metabolin includes dehydroxylation, the reduction of B- rings, C-3 epimerism and the product of 20,22- glycol cutting in mouse, rat and people.From the first principle, and above, alkylation caps the example for improving metabolic stability, and sterol of casting off a skin alkylation ether should be easier to restore from dehydroxylation, oxidation cutting and conjugation reaction than corresponding non-ether;O- must be carried out first takes off alkyl step.
It is to improve a kind of effective means that the physicochemical property of sterol of casting off a skin especially is metabolized that OH, which is capped,.A kind of overall balance can be realized by alkylation:In order to improve defective property (metabolism is unstable, remove), regulate and control excessive property (i.e. water-soluble and hydrophily).This need not sacrifice effect and be achieved that.
Semi-synthetic sterol of casting off a skin is as medicine.Steroids, including sterol of casting off a skin represent the gene switching part in addition to diacyl hydrazide, and it is another chemical type available for the switching system based on EcR.
Alkylation strategy disclosed by the invention has regulated and controled the ADME properties of influence bioavailability and medicine delivery parameter.22-O- alkylations represent a kind of modification.Such alkylation provides the gene therapy that modified form steroid activator is used to switch activation.By being methylated to sterol hydroxyl of specifically casting off a skin, we establish the physicochemical property of the pharmacology correlation of the sterol of casting off a skin of improvement, and maintain or improve the effect for selected EcR.
Hydroxyl, which is added, in 2,3,14,20 and 22 sites improves effect, and the hydroxylating in 25 sites reduces effect.However, the CfEcR and Atyiplex canescen sterone activation Bemisia argentifolii BaEcR of the activation E274V/V390I/Y410E mutation of some part/EcR compositions for peeling off, such as cyasterone, show the direction design that relative effectivenes invert and show orthogonal gene switching.Steroids-tail contact residues V411 and M502 is explained corresponding to two threonines in BaEcR in the CfEcR that effect reversion between both ligand/receptors pair can be mutated with E274V/V390I/Y410E.In general, Lepidoptera and non-Lepidoptera can mutually be made a distinction by CfEcR-V411 V to T/N/S change.Another effect reversion is also observed in E274V/V390I/Y410E mutant and carinula element B activation Aedes Aegypti (Aa) EcR for the CfEcR that cyasterone is acted on.
Embodiment 2
In a common double hybrid gene switching mode, we test the vigor that a set of 42 steroids represent 10 EcR of 9 kinds of arthropod species to one group;From BIIThe data of test and VGECR/RXR gene switchings are illustrated in the text.Trend and the reversion of uncommon effect are also arranged in the table.Compare EcR sequences, section out the contact residues from existing crystal structure (LBD comes from Lepidoptera noctuid [Hv], Semiptera Bemisia tabaci [Bt] and beetle red flour beetle [Tc]), and marked substituent on part change and acceptor on effect correlation between residue pattern.SAR outliers disclose a part matched somebody with somebody in volumetric data set.Identification effect is inverted for building orthogonal gene switching.
We identify new receiving and rubbed steroids/EcR compositions of level and subnanomole level.We also illustrate the more extensive EcR garbled datas on several rare steroids.Assess the responsibility of the EcR sequences in double cross gene switching pattern, Basal activity and dynamic range.Two undesirable steroids/EcR orthogonalities have also been identified and assessed with regard to EcR LBD sequences.

As a result
The screening collection of 42 steroids has been listed in Fig. 9,10 and 11.Maximum steroids subset is in 2-, 3-, 5-, 11-, 14-, 20-, the hydroxylating state in 22- and 25- sites and methylating upper variant (Fig. 9) for 2-, 3-, 14-, and 22- site.The yield in the second subset of steroids includes selection side chain modification, including dilution, alkylation and chain-ring fusion (Figure 10).3rd and last subset comprising uncommon structure change steroids and a brassinosteroid (iso- high rape plain lactone) (Figure 11).
Gene switching system is that each of (Figure 12) is built from 10 difference EcR, and uses double cross form:GAL4-DBD is fused to EcR upstreams and VP16 activation structures domain and is fused to the upstream of a RXR-USP chimera, pM and pVP16 plasmids are respectively adopted and go to gene switching system wink in NIH 3 T 3 cells in vitro.Using luciferase as reporter gene, it is transferred to pFRLUC carriers.Dose response curve is obtained from 43 steroids collection.Obtain EC50Be worth and be shown in Figure 13 (Lepidoptera) and Figure 14 (non-Lepidoptera) in.Second steroids gene switching EC50Data set, the main data comprising the subset from six steroids ether but the data for also including several natural steroids in baseset, are also recorded in the identical gene switching system in 3T3cells.The test result of these data also including the use of VgEcR/RXR systems, is shown in Figure 15 and Figure 16
Effect is determined with three kinds of modes.First method is directly from photometer record relative light unit (RLU).Second method is ratios of the RLU to background RLU of test ligand concentration, i.e. fold induction (FI).The ratio for the maximum FI that the maximum FI of given part of the third method to be observed in any concentration is observed to diacyl hydrazide N- (2- ethyl -3- methoxy-benzyls)-N '-(3,5- xyloyl)-N '-tertiary butyl hydrazine.These values are input in Figure 13-16 as RMFI (relative maximum fold induction).As the index of the basal expression of each switching system, background RLU has been listed in last column of every table.
PoA/NcEcR combination shows EC50=0.3nM (RMFI=1).In addition, PoA activated bs mEcR shows EC50=0.11 μM, RMFI=0.98, diacyl hydrazide is with reference to FI=1776, background FI=3.And-the CfEcR of PoA activation E274V/V390I/Y410E mutation shows EC50=0.11 μM, RMFI=0.52, diacyl hydrazide is with reference to FI=4393, background FI=2.However, 20E does not in fact show the response to CfEcR.
Being summarized in Figure 17 stacked line figure for steroids effect/acceptor response is provided, and it describes selected steroids to the-log (EC of the every kind of EcR types sorted by system50).Cross means intersect the effect reversion shown between two ligand-receptors pair of cross-pair side.For example, the CfEcR and Atyiplex canescen sterone/BaEcR of cyasterone/E274V/V390I/Y410E mutation;And the CfEcR and carinula element B/AaEcR of cyasterone/E274V/V390I/Y410E mutation.The dose response curve of the two systems is shown in Figure 18 and Figure 19.CfEcR/BaEcR couples of-log (EC of E274V/V390I/Y410E mutation50) p- log (EC50) figure shows in fig. 20.
Collected screening collection represents structure and chemical differences, including hydroxylating quantity and the difference in site, the linear C of saturation8Side chain, cis- A/B- rings connection and 7- alkene -6- ketone chromophories.Plant steroids Atyiplex canescen sterone carries and is connected to C24Pyrroles's 2- carboxyls.This compound is for fruit bat BIICell line has very high biologic viability (EC50=5.3 × 10-10M).In this biological test, the steroids of all tests all shows some vigor, EC50Across about 6 orders of magnitude (Figure 14).
A series of 20E and PoA methyl ether are screened (Figure 15 and 16) for multiple acceptors.
PoA and 20E will compare Lepidoptera more effectively to non-Lepidoptera acceptor.Due to Y410E mutation, the CfEcR of Lepidoptera E274V/V390I/Y410E mutation also has the modified regions of a sterol tail of casting off a skin.This mutation and V390I mutation so that E274V/V390I/Y410E mutation-CfEcR prefers Lepidoptera EcR.
The happy sterone A of PoA, rice, stachysterone C and different stachysterone C are the active steroids (Figure 13 and 14) relative to surveyed EcR collection.It all carries hydrophobic tail.And cyasterone some selectivity be directed to Lepidoptera EcR, Atyiplex canescen sterone selectivity be directed to non-Lepidoptera.Similarly, the vigor of ajugasterone C higher in non-lepidopteran species except for BaEcR, the usual RMFI values of Atyiplex canescen sterone weaker (AaEcR and AmaEcR) or does not have.
Six semi-synthetic steroids ethers coordinate selected natural sterol of casting off a skin to be tested (Figure 15 and 16) in 3T3 fibroblasts are substituted.In general, can have following observation result:CfEcR and 20E 3- oxygen-methyl ether of E274V/V390I/Y410E mutation, remains or even obtains effect.Other ethers lose effect, such as MsEcR and 20E 3- methyl ethers, 20E 22- methyl ethers and 20E3,22- oxygen-dimethyl ether.
Steroids effect and effect can be suitable with diacyl hydrazide (N- (2- ethyl -3- methoxyphenyls)-N '-(3,5- xyloyl)-N '-tertiary butyl hydrazine) in the EcR of engineering.For example, to units nM AaEcR activator, PoA and diacyl hydrazide all effect are very high.However, PoA is maximally efficient to Nc, Aa and Ama EcR (0.3-2nM), and diacyl hydrazide to Lepidoptera acceptor (3-20nM) more effectively.Loose sterone is to the EcR of all tests less than μm ol grades effectively, but diacyl hydrazide is effective at μm ol grade to BaEcR (6uM).Except to AmaEcR, BaEcR, and TmEcR, diacyl hydrazide is more more effective than PoA.In the acceptor studied, according to overall fold induction and background, the CfEcR and other Lepidoptera EcR of E274V/V390I/Y410E mutation optimize the most as gene switching system, and AmaEcR and TmEc ratios less optimize.
Multiple ligand/acceptor interaction.E274V/V390I/Y410E mutation-CfEcR//BaEcR are to being appropriateness correlation (R2=0.6, Fig. 4).Corresponding to-log (EC50) stacked line figure (Figure 17), and consider relative potency (RMFI), it is shown that the effect reversion between cyasterone (the CfEcR > BaEcR of E274V/V390I/Y410E mutation) and Atyiplex canescen sterone (CfEcR of BaEcR > E274V/V390I/Y410E mutation).Dose response curve (Figure 18) shows orthogonality
CfEcR//carinula element B/AaEcR dyads doing the trick reversion (Figure 17) of cyasterone/E274V/V390I/Y410E mutation.CfEcR//AaEcR pairs of E274V/V390I/Y410E mutation is also the related (R of appropriateness2=0.6).Detection dose response curve (Figure 19) shows its EC50Interval is narrower than CfEcR//Atyiplex canescen sterone/BaEcR systems of cyasterone/E274V/V390I/Y410E mutation.
Gene switching application ligand inducible gene expression system is expressed available for characteristic in functional genome, drug development, biotherapeutic protein production, genetically modified plants and animal, system and synthetic biology, cell engineering and gene therapy.
At least two steroidal ligands have had shown that feasibility:PoA and meter Le sterones A.In non-natural, non-steroids, it has been demonstrated that the effect of acid amides ketone and tetrahydroquinoline chemical type.In diacyl hydrazide family part, some parts can activate the switch based on engineering EcR in the concentration of sub- nanomole level.Opposite, steroids is with free hydroxyl and is easily metabolized.The suitable effective components of more ADME can be made again by several in these hydroxyls.
Bio-pharmaceutical needs multi-breal switch.In cancer, while controlling the function of several deleterious genes critically important in disease suppression.In order to gear to actual circumstances, multi-breal switch must be strength and as simple as possible in the range of engineering parameter allows.In the switch based on EcR, it has been reported that steroids/diacyl hydrazide and the basic composition of the THQ/ diacyl hydrazide diploids (.PNAS such as Kumar 200299:14710-15;The .J Biol such as Kumar Chem 2004279:27211-18).Cyasterone disclosed by the invention/Atyiplex canescen sterone and the plain B system of cyasterone/carinula represent the orthogonal gene switching based on steroids.
